CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 61/287,795, filed Dec. 18, 2009.

FIELD OF INVENTION

The present application relates to perfume compositions, delivery systems comprising such perfumes products comprising such perfumes and/or delivery systems, and processes for making and using same.

BACKGROUND OF THE INVENTION

It is well known that detergent perfumes are less effective in washing conditions where the level of soil is high—for examples in warmer countries where levels of soil, for example, body soil, accumulation on fabrics are higher, or in geographies where wash water is recycled for reuse or where the wash process may be less efficient e.g handwash versus machine washing—or where the washing temperature is low—due to decreased performance of traditional laundry detergents in cold water. Without wishing to be limited by theory, it is believed that perfume materials, the majority of which are relatively hydrophobic, are attracted to high levels of hydrophobic soil in such wash solutions, rendering them more likely to be washed away with the soiled water (and therefore wasted). Moreover, in high soil conditions or in cold water the removal of the soil from fabrics is less effective, and soil residues can be left on the fabrics. The inventors have found that specific combinations of perfume raw materials (PRM's) provide superior odour masking/reduction of fabric odour even—when soil is left on the fabrics after washing. A potential draw back with such perfume compositions is that materials used in such compositions can have an undesired harsh, odour when used, neat, at high levels or when high residual levels of such materials are present on a situs, for example, damp fabrics. Thus, the inventors recognized that employing such perfumes via a perfume delivery system, for example, encapsulating such perfume compositions as described herein, further improves perfume performance under high soil conditions as the encapsulation decreases the interaction of the perfume raw materials with the soil and the appropriate level of perfume is applied to a situs as too much is not washed away with the soil nor do excessive levels of residual perfume materials build up on such sites.

SUMMARY OF THE INVENTION

The present application relates to perfume compositions, delivery systems comprising such perfumes products comprising such perfumes and/or delivery systems, and processes for making and using same.

Perfume Delivery Systems

As disclosed, the benefits of the perfumes disclosed herein may be further enhanced by employing a perfume delivery system to apply such perfumes. Non-limiting examples of suitable perfume delivery systems, methods of making perfume delivery systems and the uses of such perfume delivery systems are disclosed in USPA 2007/0275866 A1. Such perfume delivery systems include:

Polymer Assisted Delivery (PAD): This perfume delivery technology uses polymeric materials to deliver perfume materials. Classical coacervation, water soluble or partly soluble to insoluble charged or neutral polymers, liquid crystals, hot melts, hydrogels, perfumed plastics, microcapsules, nano- and micro-latexes, polymeric film formers, and polymeric absorbents, polymeric adsorbents, etc. are some examples. PAD includes but is not limited to:

-   -   Matrix Systems The fragrance is dissolved or dispersed in a         polymer matrix or particle. Perfumes, for example, may be 1)         dispersed into the polymer prior to formulating into the product         or 2) added separately from the polymer during or after         formulation of the product. Diffusion of perfume from the         polymer is a common trigger that allows or increases the rate of         perfume release from a polymeric matrix system that is deposited         or applied to the desired surface (situs), although many other         triggers are know that may control perfume release. Absorption         and/or adsorption into or onto polymeric particles, films,         solutions, and the like are aspects of this technology. Nano- or         micro-particles composed of organic materials (e.g., latexes)         are examples. Suitable particles include a wide range of         materials including, but not limited to polyacetal,         polyacrylate, polyacrylic, polyacrylonitrile, polyamide,         polyaryletherketone, polybutadiene, polybutylene, polybutylene         terephthalate, polychloroprene, poly ethylene, polyethylene         terephthalate, polycyclohexylene dimethylene terephthalate,         polycarbonate, polychloroprene, polyhydroxyalkanoate,         polyketone, polyester, polyethylene, polyetherimide,         polyethersulfone, polyethylenechlorinates, polyimide,         polyisoprene, polylactic acid, polymethylpentene, polyphenylene         oxide, polyphenylene sulfide, polyphthalamide, polypropylene,         polystyrene, polysulfone, polyvinyl acetate, polyvinyl chloride,         as well as polymers or copolymers based on         acrylonitrile-butadiene, cellulose acetate, ethylene-vinyl         acetate, ethylene vinyl alcohol, styrene-butadiene, vinyl         acetate-ethylene, and mixtures thereof.     -   “Standard” systems refer to those that are “pre-loaded” with the         intent of keeping the pre-loaded perfume associated with the         polymer until the moment or moments of perfume release. Such         polymers may also suppress the neat product odor and provide a         bloom and/or longevity benefit depending on the rate of perfume         release. One challenge with such systems is to achieve the ideal         balance between 1) in-product stability (keeping perfume inside         carrier until you need it) and 2) timely release (during use or         from dry situs). Achieving such stability is particularly         important during in-product storage and product aging. This         challenge is particularly apparent for aqueous-based,         surfactant-containing products, such as heavy duty liquid         laundry detergents. Many “Standard” matrix systems available         effectively become “Equilibrium” systems when formulated into         aqueous-based products. One may select an “Equilibrium” system         or a Reservoir system, which has acceptable in-product diffusion         stability and available triggers for release (e.g., friction).         “Equilibrium” systems are those in which the perfume and polymer         may be added separately to the product, and the equilibrium         interaction between perfume and polymer leads to a benefit at         one or more consumer touch points (versus a free perfume control         that has no polymer-assisted delivery technology). The polymer         may also be pre-loaded with perfume; however, part or all of the         perfume may diffuse during in-product storage reaching an         equilibrium that includes having desired perfume raw materials         (PRMs) associated with the polymer. The polymer then carries the         perfume to the surface, and release is typically via perfume         diffusion. The use of such equilibrium system polymers has the         potential to decrease the neat product odor intensity of the         neat product (usually more so in the case of pre-loaded standard         system). Deposition of such polymers may serve to “flatten” the         release profile and provide increased longevity. As indicated         above, such longevity would be achieved by suppressing the         initial intensity and may enable the formulator to use more high         impact or low odor detection threshold (ODT) or low Kovats Index         (KI) PRMs to achieve FMOT benefits without initial intensity         that is too strong or distorted. It is important that perfume         release occurs within the time frame of the application to         impact the desired consumer touch point or touch points.         Suitable micro-particles and micro-latexes as well as methods of         making same may be found in USPA 2005/0003980 A1. Matrix systems         also include hot melt adhesives and perfume plastics. In         addition, hydrophobically modified polysaccharides may be         formulated into the perfumed product to increase perfume         deposition and/or modify perfume release. All such matrix         systems, including for example polysaccarides and nanolatexes         may be combined with other PDTs, including other PAD systems         such as PAD reservoir systems in the form of a perfume         microcapsule (PMC). Polymer Assisted Delivery (PAD) matrix         systems may include those described in the following references:         US Patent Applications 2004/0110648 A1; 2004/0092414 A1;         2004/0091445 A1 and 2004/0087476 A1; and U.S. Pat. Nos.         6,531,444; 6,024,943; 6,042,792; 6,051,540; 4,540,721 and         4,973,422.     -   Silicones are also examples of polymers that may be used as PDT,         and can provide perfume benefits in a manner similar to the         polymer-assisted delivery “matrix system”. Such a PDT is         referred to as silicone-assisted delivery (SAD). One may         pre-load silicones with perfume, or use them as an equilibrium         system as described for PAD. Suitable silicones as well as         making same may be found in WO 2005/102261; USPA 20050124530A1;         USPA 20050143282A1; and WO 2003/015736. Functionalized silicones         may also be used as described in USPA 2006/003913 A1. Examples         of silicones include polydimethylsiloxane and         polyalkyldimethylsiloxanes. Other examples include those with         amine functionality, which may be used to provide benefits         associated with amine-assisted delivery (AAD) and/or         polymer-assisted delivery (PAD) and/or amine-reaction products         (ARP). Other such examples may be found in U.S. Pat. No.         4,911,852; USPA 2004/0058845 A1; USPA 2004/0092425 A1 and USPA         2005/0003980 A1.         Reservoir Systems: Reservoir systems are also known as a         core-shell type technology, or one in which the fragrance is         surrounded by a perfume release controlling membrane, which may         serve as a protective shell. The material inside the         microcapsule is referred to as the core, internal phase, or         fill, whereas the wall is sometimes called a shell, coating, or         membrane. Microparticles or pressure sensitive capsules or         microcapsules are examples of this technology. Microcapsules of         the current invention are formed by a variety of procedures that         include, but are not limited to, coating, extrusion,         spray-drying, interfacial, in-situ and matrix polymerization.         The possible shell materials vary widely in their stability         toward water. Among the most stable are polyoxymethyleneurea         (PMU)-based materials, which may hold certain PRMs for even long         periods of time in aqueous solution (or product). Such systems         include but are not limited to urea-formaldehyde and/or         melamine-formaldehyde. Gelatin-based microcapsules may be         prepared so that they dissolve quickly or slowly in water,         depending for example on the degree of cross-linking. Many other         capsule wall materials are available and vary in the degree of         perfume diffusion stability observed. Without wishing to be         bound by theory, the rate of release of perfume from a capsule,         for example, once deposited on a surface is typically in reverse         order of in-product perfume diffusion stability. As such,         urea-formaldehyde and melamine-formaldehyde microcapsules for         example, typically require a release mechanism other than, or in         addition to, diffusion for release, such as mechanical force         (e.g., friction, pressure, shear stress) that serves to break         the capsule and increase the rate of perfume (fragrance)         release. Other triggers include melting, dissolution, hydrolysis         or other chemical reaction, electromagnetic radiation, and the         like. The use of pre-loaded microcapsules requires the proper         ratio of in-product stability and in-use and/or on-surface         (on-situs) release, as well as proper selection of PRMs.         Microcapsules that are based on urea-formaldehyde and/or         melamine-formaldehyde are relatively stable, especially in near         neutral aqueous-based solutions. These materials may require a         friction trigger which may not be applicable to all product         applications. Other microcapsule materials (e.g., gelatin) may         be unstable in aqueous-based products and may even provide         reduced benefit (versus free perfume control) when in-product         aged. Scratch and sniff technologies are yet another example of         PAD. Perfume microcapsules (PMC) may include those described in         the following references: US Patent Applications: 2003/0125222         A1; 2003/215417 A1; 2003/216488 A1; 2003/158344 A1; 2003/165692         A1; 2004/071742 A1; 2004/071746 A1; 2004/072719 A1; 2004/072720         A1; 2006/0039934 A1; 2003/203829 A1; 2003/195133 A1; 2004/087477         A1; 2004/0106536 A1; and U.S. Pat. Nos. 6,645,479 B1; 6,200,949         B1; 4,882,220; 4,917,920; 4,514,461; 6,106,875 and 4,234,627,         3,594,328 and US RE 32713.         Molecule-Assisted Delivery (MAD): Non-polymer materials or         molecules may also serve to improve the delivery of perfume.         Without wishing to be bound by theory, perfume may         non-covalently interact with organic materials, resulting in         altered deposition and/or release. Non-limiting examples of such         organic materials include but are not limited to hydrophobic         materials such as organic oils, waxes, mineral oils, petrolatum,         fatty acids or esters, sugars, surfactants, liposomes and even         other perfume raw material (perfume oils), as well as natural         oils, including body and/or other soils. Perfume fixatives are         yet another example. In one aspect, non-polymeric materials or         molecules have a CLogP greater than about 2. Molecule-Assisted         Delivery (MAD) may also include those described in U.S. Pat. No.         7,119,060 and U.S. Pat. No. 5,506,201.         Cyclodextrin (CD): This technology approach uses a cyclic         oligosaccharide or cyclodextrin to improve the delivery of         perfume. Typically a perfume and cyclodextrin (CD) complex is         formed. Such complexes may be preformed, formed in-situ, or         formed on or in the situs. Without wishing to be bound by         theory, loss of water may serve to shift the equilibrium toward         the CD-Perfume complex, especially if other adjunct ingredients         (e.g., surfactant) are not present at high concentration to         compete with the perfume for the cyclodextrin cavity. A bloom         benefit may be achieved if water exposure or an increase in         moisture content occurs at a later time point. In addition,         cyclodextrin allows the perfume formulator increased flexibility         in selection of PRMs. Cyclodextrin may be pre-loaded with         perfume or added separately from perfume to obtain the desired         perfume stability, deposition or release benefit. Suitable CDs         as well as methods of making same may be found in USPA         2005/0003980 A1 and 2006/0263313 A1 and U.S. Pat. Nos.         5,552,378; 3,812,011; 4,317,881; 4,418,144 and 4,378,923.         Starch Encapsulated Accord (SEA): The use of a starch         encapsulated accord (SEA) technology allows one to modify the         properties of the perfume, for example, by converting a liquid         perfume into a solid by adding ingredients such as starch. The         benefit includes increased perfume retention during product         storage, especially under non-aqueous conditions. Upon exposure         to moisture, a perfume bloom may be triggered. Benefits at other         moments of truth may also be achieved because the starch allows         the product formulator to select PRMs or PRM concentrations that         normally cannot be used without the presence of SEA. Another         technology example includes the use of other organic and         inorganic materials, such as silica to convert perfume from         liquid to solid. Suitable SEAs as well as methods of making same         may be found in USPA 2005/0003980 A1 and U.S. Pat. No. 6,458,754         B1.         Zeolite & Inorganic Carrier (ZIC): This technology relates to         the use of porous zeolites or other inorganic materials to         deliver perfumes. Perfume-loaded zeolite may be used with or         without adjunct ingredients used for example to coat the         perfume-loaded zeolite (PLZ) to change its perfume release         properties during product storage or during use or from the dry         situs. Suitable zeolite and inorganic carriers as well as         methods of making same may be found in USPA 2005/0003980 A1 and         U.S. Pat. Nos. 5,858,959; 6,245,732 B1; 6,048,830 and 4,539,135.         Silica is another form of ZIC. Another example of a suitable         inorganic carrier includes inorganic tubules, where the perfume         or other active material is contained within the lumen of the         nano- or micro-tubules. Preferably, the perfume-loaded inorganic         tubule (or Perfume-Loaded Tubule or PLT) is a mineral nano- or         micro-tubule, such as halloysite or mixtures of halloysite with         other inorganic materials, including other clays. The PLT         technology may also comprise additional ingredients on the         inside and/or outside of the tubule for the purpose of improving         in-product diffusion stability, deposition on the desired situs         or for controlling the release rate of the loaded perfume.         Monomeric and/or polymeric materials, including starch         encapsulation, may be used to coat, plug, cap, or otherwise         encapsulate the PLT. Suitable PLT systems as well as methods of         making same may be found in U.S. Pat. No. 5,651,976.

Rheology Modifier

The liquid compositions of the present invention may comprise a rheology modifier. The rheology modifier may be selected from the group consisting of non-polymeric crystalline, hydroxy-functional materials, polymeric rheology modifiers which impart shear thinning characteristics to the aqueous liquid matrix of the composition. In one aspect, such rheology modifiers impart to the aqueous liquid composition a high shear viscosity, at 20 sec⁻¹ shear rate and at 21° C., of from 1 to 7000 cps and a viscosity at low shear (0.5 sec⁻¹ shear rate at 21° C.) of greater than 1000 cps, or even 1000 cps to 200,000 cps. In one aspect, for cleaning and treatment compositions, such rheology modifiers impart to the aqueous liquid composition a high shear viscosity, at 20 sec⁻¹ and at 21° C., of from 50 to 3000 cps and a viscosity at low shear (0.5 sec⁻¹ shear rate at 21° C.) of greater than 1000 cps, or even 1000 cps to 200,000 cps. Viscosity according to the present invention is measured using an AR 2000 rheometer from TA instruments using a plate steel spindle having a plate diameter of 40 mm and a gap size of 500 μm. The high shear viscosity at 20 sec⁻¹ and low shear viscosity at 0.5sec⁻¹ can be obtained from a logarithmic shear rate sweep from 0.1 sec⁻¹ to 25 sec⁻¹ in 3 minutes time at 21° C. Crystalline hydroxyl functional materials are rheology modifiers which form thread-like structuring systems throughout the matrix of the composition upon in situ crystallization in the matrix. Polymeric rheology modifiers are preferably selected from polyacrylates, polymeric gums, other non-gum polysaccharides, and combinations of these polymeric materials.

Generally the rheology modifier will comprise from 0.01% to 1% by weight, preferably from 0.05% to 0.75% by weight, more preferably from 0.1% to 0.5% by weight, of the compositions herein.

Structuring agents which are especially useful in the compositions of the present invention may comprise non-polymeric (except for conventional alkoxylation), crystalline hydroxy-functional materials which can form thread-like structuring systems throughout the liquid matrix when they are crystallized within the matrix in situ. Such materials can be generally characterized as crystalline, hydroxyl-containing fatty acids, fatty esters or fatty waxes. In one aspect, rheology modifiers include crystalline, hydroxyl-containing rheology modifiers include castor oil and its derivatives. In one aspect, rheology modifiers include may be hydrogenated castor oil derivatives such as hydrogenated castor oil and hydrogenated castor wax. Commercially available, castor oil-based, crystalline, hydroxyl-containing rheology modifiers include THIXCIN™ from Rheox, Inc. (now Elementis).

Other types of rheology modifiers, besides the non-polymeric, crystalline, hydroxyl-containing rheology modifiers described heretofore, may be utilized in the liquid detergent compositions herein. Polymeric materials which provide shear-thinning characteristics to the aqueous liquid matrix may also be employed.

Suitable polymeric rheology modifiers include those of the polyacrylate, polysaccharide or polysaccharide derivative type. Polysaccharide derivatives typically used as rheology modifiers comprise polymeric gum materials. Such gums include pectine, alginate, arabinogalactan (gum Arabic), carrageenan, gellan gum, xanthan gum and guar gum.

If polymeric rheology modifiers are employed herein, a preferred material of this type is gellan gum. Gellan gum is a heteropolysaccharide prepared by fermentation of Pseudomonaselodea ATCC 31461. Gellan gum is commercially marketed by CP Kelco U.S., Inc. under the KELCOGEL tradename.

A further alternative and suitable rheology modifier include a combination of a solvent and a polycarboxylate polymer. More specifically the solvent may be an alkylene glycol. In one aspect, the solvent may comprise dipropylene glycol. In one aspect, the polycarboxylate polymer may comprise a polyacrylate, polymethacrylate or mixtures thereof. In one aspect, solvent may be present, based on total composition weight, at a level of from 0.5% to 15%, or from 2% to 9% of the composition. In one aspect, polycarboxylate polymer may be present, based on total composition weight, at a level of from 0.1% to 10%, or from 2% to 5%. In one aspect, the may comprise mixture of dipropylene glycol and 1,2-propanediol. In one solvent component aspect, the ratio of dipropylene glycol to 1,2-propanediol may be 3:1 to 1:3, or even 1:1. In one aspect, the polyacrylate may comprise a copolymer of unsaturated mono- or di-carbonic acid and C₁-C₃₀ alkyl ester of the (meth) acrylic acid. In another aspect, the rheology modifier may comprise a polyacrylate of unsaturated mono- or di-carbonic acid and C₁-C₃₀ alkyl ester of the (meth) acrylic acid. Such copolymers are available from Noveon Inc under the tradename Carbopol Aqua 30®.

In the absence of rheology modifier and in order to impart the desired shear thinning characteristics to the liquid composition, the liquid composition can be internally structured through surfactant phase chemistry or gel phases.

Test Methods

It is understood that the test methods that are disclosed in the Test Methods Section of the present application should be used to determine the respective values of the parameters of Applicants' invention as such invention is described and claimed herein.

Perfume Evaluation Test

1) The test is a 2 product test only A vs B since we compare the performance on soiled garments which have been divided in two.

2) Use a soiled load comprised of dirty/heavily soiled items obtained from consumers and divide each garment in two.

Machine A is filled with 4 half pillowcases

-   -   4 half hand towels     -   4 half dish towels     -   4 half T-shirts

Machine B is filled with the corresponding halves of the garments in Machine A.

3) No suds suppressor is added in this test.

4) The two halves of each garment are graded versus one another for a) perfume impact on a +10/−10 scale b) presence of malodour (on a 0-4 scale—where 0=no malodour and 432 very strong malodour) and c) perfume character on A-D scale where A=no change, B=slight change, C=change, D=significant change. We typically consider perfume impact as the key measure.
